Detailed Description
In order to make those skilled in the art better understand the technical solutions in the present specification, the technical solutions in the embodiments of the present specification will be clearly and completely described below with reference to the drawings in the embodiments of the present specification, and it is obvious that the described embodiments are only a part of the embodiments of the present specification, and not all of the embodiments. All other embodiments obtained by a person skilled in the art based on the embodiments in the present specification without any inventive step should fall within the scope of protection of the present specification.
Referring to fig. 1, in some embodiments of the present disclosure, a parking space guidance system may include a plurality of parking space guidance nodes and a server. The parking space guidance nodes can be arranged at each intersection in the parking lot to be used for collecting images of vehicles entering and exiting from the corresponding intersection in the parking lot; the image carries a vehicle identifier, a node identifier and an acquisition channel identifier so as to be processed by a server conveniently; each parking space guidance node can be provided with a plurality of image acquisition channels. The server may be configured to determine, from an image provided by the parking space guidance node in the parking lot, a target parking space guidance node and a target acquisition channel corresponding to a last time when the target vehicle is acquired before entering a steady state, and determine a parking space occupation state of a corresponding parking space partition in the parking lot according to a position of the target parking space guidance node in the parking lot and an acquisition direction of the target acquisition channel.
Therefore, in the embodiments provided in the present specification, the parking space detection in the parking lot is implemented by the parking space guidance nodes arranged at each intersection in the parking lot, and the parking space partition is used as the detection unit. Therefore, compare with a parking stall detector among the prior art and detect a parking stall, this specification embodiment can reduce parking stall guide node's use quantity by a wide margin to can reduce parking stall guide system's implementation cost by a wide margin.
In an exemplary embodiment of the present specification, the distribution of the parking space guidance nodes in the parking lot may be as shown in fig. 2. In fig. 2, each intersection in the parking lot is provided with a parking space guidance node, the number of image acquisition channels of each parking space guidance node is adapted to the type of the intersection where the parking space guidance node is located, and each image acquisition channel forms a certain angle with the horizontal plane and can be adjusted according to the height of the underground parking lot, so that the real traffic condition of the intersection can be accurately acquired. For example, if the type of the intersection at the entrance and exit shown in fig. 2 is an intersection, the number of the image capturing channels of the parking space guidance node at the position is four, and the capturing direction of each image capturing channel faces to one intersection of the intersection. Therefore, the whole parking lot can be divided into the grid sections through the parking space guide nodes, namely, one parking space section can be determined by every two adjacent parking space guide nodes. For example, the slot guidance nodes A3 and a2 shown in fig. 2 may determine a slot partition as shown by the dotted line in fig. 2. In an exemplary embodiment of the present specification, when the parking lot is a layered structure, a parking space guidance node may also be provided at a layered intersection, for example, as shown in fig. 3.
In some embodiments of the present disclosure, when a vehicle enters a parking lot for parking, or when the vehicle exits from a parking space of the parking lot, the vehicle passes through a parking space guidance node every time the vehicle passes through the parking space guidance node, the parking space guidance node collects an image of the vehicle and uploads the image to the server in real time. Generally, a vehicle does not move for a short time after being finally parked in a certain parking space in a parking lot; correspondingly, the parking space guide node in the parking lot can not acquire the image of the vehicle and send the image to the server, and at the moment, the vehicle can be considered to enter a stable state. Similarly, when a vehicle exits from a parking space of the parking lot, the vehicle generally cannot return to the parking lot in a short time; correspondingly, the parking space guide node in the parking lot can not acquire the image of the vehicle and send the image to the server, and at the moment, the vehicle can be considered to enter a stable state. Thus, it is possible for the server to confirm that a vehicle has entered a steady state if a new image for the vehicle is not received within a preset time interval after receiving the first image of the vehicle.
In some embodiments of the present disclosure, the server may save a latest image for images containing the same vehicle identifier by replacing or overwriting the latest image. When a vehicle corresponding to a certain vehicle identifier enters a stable state, the server can determine a corresponding target parking space guide node and a target acquisition channel before the vehicle enters the stable state and when the vehicle is acquired last time according to the currently stored image carrying the vehicle identifier. Since the position of each parking space guidance node in the parking lot and the acquisition direction of each image acquisition channel of each parking space guidance node are known (for example, as shown in fig. 2), the parking space occupation state of the corresponding parking space partition in the parking lot can be determined according to the position of the target parking space guidance node in the parking lot and the acquisition direction of the target acquisition channel.
In an exemplary embodiment of the present specification, as shown in fig. 6, a vehicle enters a parking space (e.g., a parking space pointed by an arrow end with a dotted arrow in fig. 6) in the parking lot from a certain entrance/exit of the parking lot. In the process, the vehicle is sequentially collected into images by the lower collecting channel of the parking space guide node a1, the upper collecting channel of the parking space guide node a1, the lower collecting channel of the parking space guide node a2, the upper collecting channel of the parking space guide node a2 and the lower collecting channel of the parking space guide node A3. After the vehicle enters the steady state, the parking space guide node a3 and the lower acquisition channel thereof are respectively the target parking space guide node and the target acquisition channel corresponding to the last acquisition time before the vehicle enters the steady state. According to the position of the parking space guidance node A3 and the collection direction of the lower collection channel of the parking space guidance node A3, the server may confirm that the vehicle is parked at a parking space on both sides of the road segment corresponding to the lower collection channel of the parking space guidance node A3 (i.e., at a parking space in the parking space partition within the dotted-dashed line range in fig. 6). Accordingly, the server may store the parking record (i.e., store the vehicle identifier of the vehicle parked in the parking space partition), and update the parking space occupation status of the parking space partition accordingly.
In another exemplary embodiment of the present specification, as shown in fig. 7, when a vehicle exits the parking lot from a space in the parking lot (e.g., a space pointed by the non-arrow end with the dotted arrow in fig. 7). In the process, the vehicle is sequentially collected into images by the lower collecting channel of the parking space guide node A3, the upper collecting channel of the parking space guide node a2, the lower collecting channel of the parking space guide node a2, the upper collecting channel of the parking space guide node a1 and the lower collecting channel of the parking space guide node a 1. After the vehicle enters the steady state, the parking space guide node a1 and the lower acquisition channel thereof are respectively the target parking space guide node and the target acquisition channel corresponding to the last acquisition time before the vehicle enters the steady state. Since the parking space guidance node a1 is located at the entrance/exit position of the parking lot and the collection direction of the lower collection channel of the parking space guidance node a1 is directed to the exit of the parking lot, the server can confirm that the vehicle has exited the parking lot. Correspondingly, the server can update the parking space occupation state of the corresponding parking space partition according to the parking record corresponding to the vehicle identification of the vehicle.
Referring to fig. 4, in some embodiments of the present disclosure, a parking space guidance node may include a multi-channel image acquisition module, a main control module, and a data transmission module.
The multi-channel image acquisition module can be used for acquiring images of vehicles entering and leaving a corresponding intersection in a parking lot. In an exemplary embodiment, the multi-channel image capturing module may be composed of a plurality of cameras (or other components with image capturing function), and each camera points to a different capturing direction; the number of the cameras is adapted to the type of the intersection where the parking space guide nodes are located.
The master control module may be configured to initiate a data transmission request including the image. In an exemplary embodiment, the main control module may include, but is not limited to, a single chip microcomputer, a Micro Controller Unit (MCU), a Digital Signal Processor (DSP), a Programmable Logic Controller (PLC), and the like. The specification does not limit this, and the specific choice can be selected as required.
The data transmission module may be configured to send the image to a server when receiving the data sending request; the server determines a target parking space guide node and a target acquisition channel corresponding to the last time when the target vehicle is acquired before entering a stable state from an image provided by the parking space guide node in the parking lot, and determines the parking space occupation state of a corresponding parking space partition in the parking lot according to the position of the target parking space guide node in the parking lot and the acquisition direction of the target acquisition channel. In an exemplary embodiment, the data transmission module may be, for example, a wireless communication module based on one or more wireless communication protocols. The wireless communication protocol may include, but is not limited to, a narrowband Internet of Things (NB-IoT) protocol, and the like.
In some embodiments of this specification, as shown in fig. 4, the parking space guidance node may further include a projection module. The projection module may be configured to project the guidance information onto a road surface at a corresponding intersection when receiving a projection request carrying the guidance information sent by the main control module. When the main control module confirms that the specified event occurs, the main control module may send a projection request carrying the guidance information to the projection module. The specified event may be, for example, that the main control module receives a guidance message, and the like, which is not limited in this specification and may be specifically set as needed.
In an exemplary embodiment, the guidance information may be, for example, a guidance direction. When a vehicle enters a parking lot, the parking space guide node at the entrance and the exit of the parking lot firstly collects the image of the vehicle and sends the image to the server. Correspondingly, the server can confirm the parking space guide node which collects the vehicle image according to the image, generate a guide direction according to the current parking space occupation state of the parking space subareas around the parking space guide node and send the guide direction to the parking space guide node, so that the main control module can receive the guide information. Accordingly, the projection module may project the guiding direction onto the road surface at the corresponding intersection as shown in fig. 9 to actively recommend parking spaces for the vehicle, so as to guide the vehicle to park. When the vehicle does not travel according to the guidance direction, when the vehicle travels to the vicinity of the next parking space guidance node and the next parking space guidance node receives the guidance direction sent by the server, the guidance direction may be projected onto the road surface at the corresponding intersection to continue parking guidance for the vehicle.
In another exemplary embodiment, the guidance information may also be a guidance path. When the server receives a parking position query request carrying a vehicle identifier sent by a parking space guide node, a parking partition corresponding to the vehicle identifier can be matched from a parking record according to the vehicle identifier, a guide path is generated according to the position of the parking partition and the position of the parking space guide node, and a query result containing the guide information is returned to the parking space guide node. Accordingly, the projection module may project the guidance path onto the road surface at the intersection corresponding to the parking space guidance node as shown in fig. 10, so as to facilitate the user to quickly locate and reach the parking position where the target vehicle is parked (i.e., guide the user to seek the vehicle in the reverse direction).
Please refer to fig. 4, in some embodiments of the present specification, the parking space guidance node may further include a human-computer interaction module. The human-computer interaction module can be used for providing the query request to the main control module when receiving the query request of a user, so that the main control module provides the query request to the server through the data transmission module; and when receiving the query result provided by the main control module, providing the query result to the user. In an exemplary embodiment, the human-computer interaction module may be, for example, a human-computer voice interaction module, and the human-computer voice interaction module may perform voice interaction with the user to provide the query request of the user to the main control module, and may provide the query result provided by the main control module to the user in the form of voice, for example, as shown in fig. 8. In another exemplary embodiment, the human-computer interaction module may also be a User Interface (UI), and the User Interface may perform image-text interaction with the User to provide the query request of the User to the main control module, and may display the query result provided by the main control module to the User in an image-text form. It should be understood that the present specification is not limited thereto, and other human-computer interaction modes may be specifically adopted according to the needs.
In some embodiments of the present description, the query request may include a remaining available space query request in a parking lot or a parking location query request carrying a vehicle identification, etc. The specific property can be specifically selected according to needs.
In other embodiments of this specification, the parking space guidance node may further include a traffic light. The traffic signal lamp can be used for outputting a corresponding light signal according to the control signal when receiving the control signal sent by the main control module so as to indicate traffic of a corresponding intersection. For example, when vehicles and/or pedestrians exist on a plurality of channels of the intersection where the parking space guidance node is located, the main control module can control the traffic signal lamp to flash yellow to prompt the vehicles and the pedestrians to pay attention to safety. When vehicles and/or pedestrians are/is arranged on only one channel of the intersection where the parking space guide node is located, the main control module can control the traffic signal lamp to display a green light. And so on.
In other embodiments of this specification, the parking space guidance node may further include an environment monitoring sensor. The environment monitoring sensor can be used for monitoring the environment around the corresponding intersection and providing the monitoring result to the main control module; and the main control module provides the data to the server through the data transmission module so that the server determines whether to start a corresponding coping strategy according to the monitoring result. In some exemplary embodiments, the environmental monitoring sensors may include, but are not limited to, any one or more of a fire detector, a temperature sensor, a humidity sensor, a brightness sensor, a carbon dioxide sensor, and the like. For example, in the case of a fire detector, when it is determined that a fire occurs in a parking lot based on the fire detector, the server may control a fire extinguishing system in the parking lot to initiate fire extinguishing; for another example, taking an air quality monitoring sensor as an example, when it is confirmed that the concentration of carbon dioxide in the parking lot exceeds a preset threshold value based on the carbon dioxide sensor, the server may control the ventilation system in the parking lot to start; and so on.
In some embodiments of the present description, as shown in fig. 5, the server may include a data transmission module and a processing module.
The data transmission module can be used for acquiring images of vehicles entering and exiting from the corresponding intersection, which are acquired by the parking space guide nodes in the parking lot. In an exemplary embodiment, the data transmission module may be, for example, a wireless communication module based on one or more wireless communication protocols. The wireless communication protocol may include, but is not limited to, a narrowband internet of things protocol, and the like.
The processing module may be configured to determine, from the image, a target parking space guidance node and a target collection channel corresponding to a last time when a target vehicle is collected before entering a steady state, and determine a parking space occupation state of a corresponding parking space partition in the parking lot according to a position of the target parking space guidance node in the parking lot and a collection direction of the target collection channel. In some exemplary embodiments, the processing module may include, but is not limited to, a single chip microcomputer, a micro control unit, a digital signal processor, a programmable logic controller, and the like. The specification does not limit this, and the specific choice can be selected as required.
In some embodiments of this specification, the processing module may be further configured to, when receiving, by the data transmission module, an inquiry request sent by a client or a parking space guidance node, process the inquiry request to obtain an inquiry result, and return the inquiry result by the data transmission module, so that the client or the parking space guidance node outputs the inquiry result to a user. The query request can comprise a remaining available space query request in the parking lot or a parking position query request carrying the vehicle identification. For example, when the query request is a vacancy remaining query request and is initiated by a client, the client may output the query result as shown in fig. 11 when receiving the query result. For another example, when the query request is a parking location query request with a vehicle identifier and is initiated by a client, the client may output the query result with guidance information as shown in fig. 12 when receiving the query result.
For convenience of description, the above devices are described as being divided into various units by function, and are described separately. Of course, the functions of the various elements may be implemented in the same one or more software and/or hardware implementations of the present description.
In some embodiments of the present description, the server may be an electronic device with computing and network interaction functions; software that runs in the electronic device and provides business logic for data processing and network interaction is also possible. The client can be a desktop computer, a tablet computer, a notebook computer, a smart phone, a digital assistant, an intelligent wearable device and the like. Of course, the client is not limited to the electronic device with certain entities, and may also be software running in the electronic device.
